摘要
岩石洞室开挖施工质量标准以炮孔痕迹保存率、岩石壁面局部超、欠挖及平整度为主。通过绥中县大风口水库应急供水工程引水隧洞工程洞挖施工案例,具体分析影响引水隧洞洞挖光面爆破质量产生的原因,提出洞挖光面爆破质量控制具体措施和方法。
The bore traces of preservation rate,rock wall local super,under excavation and leveling are mainly used to evaluate the rock excavation construction quality standards.Through the diversion tunnel excavation case of emergency water supply project at Suizhong County Dafengkou reservoir,the impact reasons for the water diversion tunnel excavation blasting quality are analyzed and provide some concrete measures and methods for the tunnel smooth blasting quality control.
